Glass electrode A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. The most common application of ion-selective glass electrodes is for the measurement of pH. The pH electrode is an example of a glass electrode that is sensitive to hydrogen ions. Glass electrodes play an important part in the instrumentation for chemical analysis and physico-chemical studies.

- The sample being measured is injected into the carrier gas using a syringe and instantly vaporizes (turns into gas form). The gases that make up the sample separate out as they move along the column (orange), which contains the stationary phase (typically, it's a thin coating on the inside wall of the column).

- Type Use the correct type of glass. When heating glassware, make sure to use only glassware made of borosilicate glass (Pyrex® brand or Kimax® brand). Common glass can break, explode or shatter very easily when subjected to heat shock. Make sure to use test tubes made of borosilicate glass when heating. Not all test tubes are made of borosilicate glass. Proper Use Each type of glassware has its proper use and should be used only for its intended purpose.
